saving objects to disk

[Andy_Hollywood]

I have a 2 dimensional array which holds vectors of floats, its pretty big and i need save and restore this from disk.

Is there an easy way to do this other than reading it in and out of text files?

Cheers

Andy

use fread() fwrite() to write a binary file.

FILE *out;
float  **arr;
... fill up your array with data
out=fopen("myfile.dat","wb");
fwrite(arr, sizeof(float), numberofelements, out);
fclose(out);

// to get it back -
out=fopen("myfile.dat","rb");
fread(arr,sizeof(float), numberofelements,out);
fclose(out);
